Abstract:
OBJECTIVE To study the characteristics of pathogens and risk factors of ventilator-associated pneumonia(VAP) in our hospital to determine the prevention and treatment strategies. METHODS Prospective observation was performed in all the ventilator-related patients in 2004. RESULTS Seventy eight events of ventilator-related pneumonia among 56 cases occurred from all the 202 ventilator-related patients,the infection incidence was 98/1000VDs.The revealed important risk factors were oldness,coma,tracheotomy,use of H-2 receptor inhibitors,and prolonged mechanical ventilation.64.8% of the pathogens were G-bacilli,among which Pseudomonas aeruginosa contributed majority accounting for 22.7%,fungi accounting for 20.5%.There was wide resistance to antibiotics in G+ pathogens,including all of the isolated Staphylococcus. CONCLUSIONS VAP is caused predominantly by G-bacteria,fungi,and multiple predisposing factors.The combined treatment is necessary for control of VAP.
